Previous work of the author is amplified in this monograph, which describes a new, accurate and economical method of recording the movement of internal organs on one film. This is made possible by an adaptation of the kymograph, permitting timed exposures at successive levels and at regularly spaced intervals, with exposed portions being separated by an unexposed strip of the film. By this means, contour curves of maximal and minimal movements, particularly of the heart and the aorta, can be accurately measured. The technic is fully described. A section is devoted to diagnostic application. Results are described in studies of the heart, aorta, pericardium, diaphragm, esophagus and stomach.
